Abstract
Ayad Omar Tripoli University, Faculty of Physical Education and Sport Sciences, Tripoli-Libya Introduction It is generally known that cardiovascular, respiratory, and metabolic responses are significantly different between cycling and running when performed at the same overall metabolic rate. Although blood coagulation and fibrinolysis have been extensively studied and reviewed (El-Sayed et al. 2010), the effect of exercise modalities on blood coagulation is not known. Therefore, the aim of the present study well assess the effect of exercise modes (cycling versus running) at 70% VO2max on some blood in adults. Methods: Fingertip blood samples well removed from about ten normal healthy adults before and immediately after two separate ergometer-specific exercise trials at approximately 70% VO2max (for 45-min) on a treadmill and stationary pike; respectively. Blood will be assayed for lactate concentration (BLa, haematocrit (Hct) and haemoglobin (Hb); while citrated plasma will be analyzed for plasma viscosity and fibrinogen (Fb) if possible. Data analyses: Equipment should be available are: portable blood lactate analyser, heart rate monitor, treadmill and monark ergom
